VALENTIN JAKOB ODHNER, OF HINDAS, SWEDEN.

CALCULATING WHEEL OF CALCULATING MACHINES.

Application filed May 11,

To all whom it may concern:

Be it known that I, VALENTIN JAKOB Corinne, a subject of the King ofSweden, and resident of Turisthotellet, Hindas, in the Kingdom ofSweden, have invented certain new and useful Improvements in CalculatingWheels of Calculating Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

In calculating machines of the type disclosed in the U. S. patent to IV.T. ()dhner 511,725, February 13, 1894, the tens-pins, h undreds-pins,etc., of the calculating wheels are swingable laterally or transverselyof the wheels, owing to which fact the thickness of the wheels or thedistance between the wheels must be sufficient for the purpose.Differing from the said arrangement "the said pins according to thisinvention are swingable or movable in the plane proper of the saidwheel. Owing to the said arrangement the wheels maybe thinner or thedistance between the wheels may be reduced. As the machines have a greatnumber of calculating wheels the length of the machine can beconsiderably reduced bythe said arrangement. In connection with theshifting of the pin the present invention also relates to means forshifting the part stated in the U. S. Letters Patent No. 1,348,576,granted August 3, 1920, which closes and opens respectively the openinprovided in the calculating wheel throng which the star wheel, adaptedto lock the registering wheel, passes, while the 10-pin, etc, is inoperative position.

The accompanying drawings show some forms of execution of the invention.Figs. 1 and 3 show in a. side view one form of execution with the10-pin, etc, in inoperative and operative position respectively. Fig. 2is a cross section of the parts having the same position as shown inFig. 3. Figs. 4 and 5, Figs. 6 and 7 and Figs. 8 and 9 show in sideviews three further forms of execution with the said pin, etc, ininoperative and operative position respectively. Figs. 10 and 11 show 1ntwo different positions means for closing and opening respectively thepassage provided in the calculating wheel for the star-wheel used incombi- 1920. Serial No. 380,472.

nation with the device shown in Figs. 1 to 3 inclusive. 12 and 13 showin the same manner means for closing and opening the said passage usedin combination .h the device shown in Figs. 6 and 7. s. 14 and show inthe same manner :1; .ns for opening and closing the said pas- :ea e usedin combination with the device shown in Figs. 5 and 9. Figs. 16 and 17are sections of a calculating machine showing two positions of thedevice illustrated in Figs. 10 and 11.

- provided in the calculating 1 to 3 inclusive, a two-armed part is piv..d at 2, the one arm 3 of which forms the 10-pin, etc., and the otherarm 4 or which serves to move the said pin into cperative position. Thesaid arms 3 and are loc ted in different planes parallel to the calcuing wheel. Fig. 2. As shown in 'Ihe drawings the 3 and 4: are swingablein the plane of the calculating wheel 1. For the said reason thecalculating wheels mav be thinner than in machines provided with10-pins, etc, swingable transversely of the calculating wheels, whichresults in a reducing oi the length of the machine. The said arms arenormally held in the position shown in Fig. 1 by a leaf spring 5. 6 isthe tens-transmitting part. The said part 0 may be shifted in ordinarymanner but s so arranged, that the same, moved to its operativeposition, Fig. 3, swings the arm 4 inwards towards the calculatingwheel 1. and moves the arm or 10-pin 3 from its inoperative position,Fig.1, to its operative position, Figs. 2 and 3, in which it extendsoutside the periphery of the Wheel 1. In Figs. 4: and 5 the 10-pin 3 ismovable longitudinally in the calculating wheel 1 and is held by aspring 5 in its inner position, Fig. 4-. The said pin 3 is provided withteeth meshing with teeth provided on an arm 7, which is pivoted to thecalculating wheel 1 and normally extends outside the wheel 1. \Vhen thetens-transmitting part is in its operative position. Fig. 5, it swingsthe arm 7 inwards, during which operation the arm 7 moves the pinoutwards into its operative position by means of the described gearing.

In the form of execution shown in Figs.

6 and 7 the 10-pin 3 well as the part 8, located parallelly to the saidpin and adapted to shift the same, is movable longitudinally in thecalculating wheel 1. The pin 3 and the part 8 are connected with atwoarmed lever 9, pivoted to the calculating wheel, by means of a pinandslot-connection, so that, as the part 8is moved inwards by thetens-transmitting part 6 against the action of a spring 10, the pin 3 ismoved outwards, as shown in Fig. 7.

In Figs. 8 and 9 the pin 3 is movable longitudinally in the calculatingwheel 1 and is provided witha lateral pin 11, which engages a curvedslot 12 provided in a movable plate 18. The said plate 18 is movableperipherally on the wheel and is guided by curve shaped slots i l,engaged by pins 15 fixed in the wheel 1 and provided with heads. Atwo-armed lever 17 is pivoted at 16 to the wheel 1 and is connected by apinand slot-connection 18 with the plate 13, so that by the swinging oithe lever 17, effected by the transmitting part 6, the plate 13 is movedtowards the ri 'ht, Fig. 9, and by means oi? the curve slot 1:2 movesthe pin 3 into its operative position. A spring 5 returns the parts tothe position. shown in Fig. 8.

19, Figs. 10 and 11, designates the starwheel, described in the LetterslPatent mentioned above and bearing against the periphery of thecalculating wheel locking the registering wheel in adjusted position. 20is the ordh ary transmitting wheel, which is engaged by the pins of thecalculating wheel, brought into operative position, for shitting theregistering wheel. in orderthat the star-wheel may be able to rotate fora distance of one tooth, while the 10pin, etc, actuates the wheel. 20,an. opening 21 is provided in the periphery of the calculating wheel 1at the position of the pin 8. At the said opening 3 a plate which ispivoted at 22 to the calculating wheel 1. normally is located and bearsagainst the star-wheel 19 and locks the same, while the pin 3 ininoperative position passes the star-Wheel; As the pin is brought intooperative position in the manner stated above wi h reference to Figs. 1to 3 inclusive, the plate 23 is moved to the position shown in Fig. 11,so that the opening 9. free and the starwheel can pass :he same. Thesaid moving of the plate 523 is effected by a pin 24 provided on the arm4 and engaging a slot 25 in the plate As the pin 3 is re turned to itsinoperative position, the plate 9 is returned to the position shown inIn the arrangement shown in Figs. 12 and 13 the movable part 8 (compareFigs. 6 and 7) is connect-ed by means of a pin 26 with a plate 28movable in a guide 2? provided on the calculating wheel 1. The saidplate 28 reac es normally covers the opening 21 in the periphery of thewheel 1 but is moved to the position shown in by the described means, asthe pin 3 moved outwards to its operative position In Figs. l t and 15the plate 13 (Figs. 8 and 9) has a pr jection 29, which normally coversthe opening ill of the heel 1 but is moved, duri g the moven'i nt of theplate l3 for bringing the pin into operative position, into a po ition.lateral of the opening 521, as shown 15. so that the star wheel canpass.

in Figure 16, the member 6 pivoted to the slide is shown occupying aninactive position, that is, the arm is not acted upon by the member 6and consequently the 10-pin rests in the inactive position shown as itthe member 6 incident to the rotation of the calculating wheel in thedirection indicated by the arrow. The arm 6 is retained in this positionby the displaceable and spring actuated pin 30 which latter restsagainst one side of the shaft 31. During the continued operation. of themachine, the d t pin located in another calculating wheel (not shown) ofthe nearest interior value pass the toothed wheel 20 whereby the digitpins which have been brought into operative position advance saidtoothed wheel and the registering wheel 32 so that the same are movedinto the positions shown in Figure 1?. The above mentioned calcula 11gwheel carrying the digit pins, though not shown in the accompanyingdrawing, is fully dis closed in Patent 51%,?25 above referred to. The in33 passes the member 6 and shifts it to the position shown in Fig. 1?,the pin 30 being displacedby the shaft 31 so as to yieldingly lock themember 6 in the new position, the pin 30 bearing against the op positeside 01: the shaft 31. its the member 6 and the arm 4 are located in thesame plane, the latter will be shifted by the member 6 pressed closelyto the edge of the calculating wheel, the pin 3 being advanced intooperative position. so.that, upon continned rotation of thejwheel 1, itmeshes with the toothed wheel 20 and advances it one step. It will beunderstood that the pin 3 and the toothed wheel 20 are located in thesame plane. At the same time that the pin 6 is shifted to operativeposition, the plate 23 i moved aside so that a tooth of the star-wheel19 located in the same plane as the plate may freely pass through theopen.- ing 21 whereby said star wheel and the toothed wheel 20 and. theregistering Wheel may be advanced. The 10-pin is then moved back intoinoperative position by the spring 5.. From the foregoing it will beunderstood thatthe three groups of parts 6 and 4., 3 and 20, 19 and 23are located in three ditlerent planes, that is to say, the member 6 andthe arm 4 are located in one plane, the

I claim as movable -cart, whereby the pin iO-pin and the toothed Wheelin another plane and the star wheel 19 and the plate 23 in anotherplane.
